The theory that `` Amazon is producing 20% of the oxygen on the earth '' is an error, pointing out that oxygen will have millions of years to come

Concerns have gathered from around the world over a record number of fires in the Brazilian Amazon rainforest. On the other hand, atmospheric science experts have pointed out that the Amazon fire is certainly devastating, but it is a mistake to worry about the oxygen supply.

French President Emmanuel Macron tweeted on August 22, 2019, 'The Amazon rainforest that produces 20% of the Earth's oxygen is on fire. This is an international crisis' Called.




President Macron's tweets have collected more than 58,000 retweets and more than 161,000 likes at the time of writing, indicating that many people are highly interested in this issue .

However, Scott Denning, a professor of atmospheric science at Colorado State University, said, “The common claim that the Amazon rainforest produces 20% of the Earth's oxygen is based on misunderstanding.” “Respirable oxygen will last for millions of years.”

Denning said, “Oxygen molecules present in the atmosphere are almost entirely derived from photosynthesis by plants” and “One third of the photosynthesis performed on the ground is from the rainforest.” “The Amazon Basin Is affirming that there is the largest rainforest on earth.

However, the rainforest is not only an oxygen producer but also a consumer. While Amazon trees produce large amounts of oxygen through photosynthesis, they are constantly broken down into fallen trees and broken down into insects and microorganisms. Such a cycle of production and decomposition supports the rich ecosystem of Amazon, but enormous amounts of oxygen are consumed mainly by microorganisms in the process, and as a result, the production of oxygen by land plants is almost deducted. That.



According to Denning, sea plants are responsible for supplying oxygen instead of land plants. Marine plants such as algae and phytoplankton also produce oxygen by photosynthesis, like terrestrial plants, and are broken down by microorganisms, which consumes oxygen in the process. However, some marine plants settle on the ocean floor without being decomposed.

Denning sees only 0.0001% of the total amount of plants buried in the ocean floor and peat bog on the ground without being decomposed when converted to photosynthesis. However, as a result of the accumulation of such subtle imbalances in production and consumption in the course of living creatures over millions of years, the Earth's atmosphere now contains large amounts of oxygen.

Denning said, “Even if all the organic matter on the earth is burned out at once, only less than 1% of oxygen is consumed,” Amazon's fire has little impact on the amount of oxygen in the atmosphere. He indicated that he did not.

On the other hand, he says, “The fact that the increase in deforestation threatens the most biodiversity-rich nature on the planet is already a big problem,” and there is a need to worry about oxygen. Even if not, it emphasizes that the decline of the rainforest is a fire problem.
